Description

Technical Field

[0001] The utility model relates to the technical field of inclinometers, in particular to a self-breaking guide wheel device and an inclinometer. Background Art

[0002] Inclinometer is an instrument used to measure the top angle and azimuth of engineering structures such as boreholes, foundation pits, foundations, walls and dam slopes. Inclinometer tubes are usually installed in vertical boreholes that pass through unstable soil layers to the lower stable strata. Use a digital vertical movable inclinometer probe, control cable, guide wheel device and readout to observe the deformation of the inclinometer tube. The first observation can establish the initial section of the displacement of the inclinometer tube. Subsequent observations will show the change in section displacement when the current geological movement occurs. During the observation, the probe moves from the bottom of the inclinometer tube to the top, pausing at one meter intervals and measuring the inclination. The inclination of the probe is measured by a force-balanced measuring instrument, and the inclination can be converted into lateral displacement. Comparing the current and initial observation data, the change in lateral displacement can be determined, showing the movement displacement of the geological layer. Plotting the change in displacement can obtain a high-resolution displacement section. This section helps to determine the size, depth, direction and rate of ground movement displacement.

[0003] The inclinometers commonly used in the market are often stuck in the inclinometer tube due to deformation during use and cannot be removed, resulting in the inclinometer being scrapped and causing property losses. Utility Model Content

DETAILED DESCRIPTION

[0020] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0021] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0022] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0024] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0026] First, as Figure 1As shown, the present application provides a self-breaking guide wheel device, which includes a wheel arm 1 and guide wheels 2 rotatably mounted at both ends of the wheel arm 1, wherein the wheel arm 1 has a central axis 3 connected to an inclinometer at the center position, and the upper side wall of the wheel arm 1 has two stress grooves 4, and the two stress grooves 4 are symmetrically arranged on both sides of the central axis 3.

[0027] Specifically, in this embodiment, the wheel arm 1 is made of stainless steel, and the stress groove 4 is a V-shaped opening structure. The opening angle of the stress groove 4 is [10°-20°], and the specific opening size of the stress groove 4 is determined according to the required tension design. In this embodiment, the preferred opening angle of the stress groove 4 is 15°. The spacing d between the two stress grooves 4 is about 30 mm, and the depth h of the stress groove 4 is about 10 mm. It can be understood that if the wheel arm 1 is made of different materials, or the required tension is different, the spacing between the two stress grooves 4 and the depth of the stress groove 4 can be adjusted accordingly, and this embodiment does not impose specific restrictions.

[0029] In order to completely solve the loss caused by the inclinometer being stuck, a stress groove is opened on the wheel arm of the guide wheel device. After the inclinometer is stuck in the inclinometer tube, when the external traction force reaches the preset value, the wheel arm is broken or bent from the stress groove to ensure that the inclinometer body can be smoothly pulled out of the inclinometer tube. In this way, the inclinometer body will not be lost, and it can be reused by simply replacing the guide wheel device assembly.

[0030] Based on the same inventive concept, in the second aspect, Figure 2 As shown, the present application also provides an inclinometer, including an inclinometer body 100 and a self-breaking guide wheel device 200 as described in the first aspect and installed on the inclinometer body 100.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of the present application.
